Answer 1

Solved the issue using the following version of Angular Material npm i @angular/[email protected]

Answer 2

I had a similar issue when I was working with angular material on Stackblitz. After a bit of research, I figured out that this is due to the miss-matched version of Angular and Angular Material.

To fix this either update all of the dependencies to the latest version or choose @angular/material that is compatible with your version of Angular.

P.S.

1. My angular version was 11 and I was using Angular Material 12.

2. If you get the following error Error in turbo_modules/@angular/[email protected]/table/table-module.d.ts (8:22) disable Ivy. See this question for more details: How to fix Stackblitz ngcc error with Material Design MatTableModule?

Answer 3

This is most likely due to a mismatch between TypeScript versions that your local project installs versus the TypeScript version that @angular/material requires. Check which TypeScript version you're on in package.json and see which TypeScript version @angular/material requires.

If your local TypeScript version is behind, you will most likely have to downgrade the version of @angular/material.
